← Back to Chemical Safety

Basic information

  • Chemical formula(s): Two-part system: Part 1/2 contains \({\rm NaOH}\) (<0.2%); Part 2/2 contains D-mannitol (76%), troclosene sodium dihydrate (12%), sodium nitroprusside dihydrate (12%)
  • Other names: LCK302 Ammonium test, Sample cuvette and DosiCapZip
  • Product Code: LCK302-1 (sample cuvette), LCK302-2 (DosiCapZip)
  • International Chemical Safety Card (ICSC): N/A - multiple components (see Hach safety card)
  • Flammability: no (does not burn)
  • Description: Two-part water analysis test kit for ammonium determination. Part 1 is alkaline solution (pH 12.5), Part 2 is solid reagent mixture containing toxic components.

NFPA 704 (fire diamond)

  • Health (blue): 2 - intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury.
  • Flammability (red): 1 - must be pre-heated before ignition can occur (based on organic components).
  • Instability–reactivity (yellow): 0 - normally stable, even under fire exposure conditions.
  • Special notice (white): - - no special hazards.

Protective measures

Gloves

  • Nitrile: very good - chemical resistant protective gloves recommended for handling toxic components.
  • Butyl rubber: very good - excellent protection against sodium hydroxide and toxic reagents.
  • Natural latex or rubber: fair - adequate for brief contact but not recommended for extended use.
  • PVC: fair - provides basic protection but limited chemical resistance.

Safety goggles

  • Mandatory: Always wear safety glasses with side-shields when handling.
  • Strong alkaline solution (pH 12.5) and toxic components require eye protection.
  • Corrective glasses are not considered safety goggles.
  • Part 1/2 may cause severe eye damage, Part 2/2 causes irritation.

Clothing

  • Wear protective clothing to prevent skin contact.
  • Long sleeves and full-length pants required.
  • Closed-toe shoes mandatory.
  • Remove and wash contaminated clothing before reuse.
  • Caustic hazard: Part 1/2 contains sodium hydroxide which causes severe burns.

Respiratory protection

  • Use only in well-ventilated areas.
  • Toxic if inhaled - avoid breathing vapors from Part 2/2.
  • Contact with acids liberates toxic gas - ensure proper ventilation.
  • Use appropriate respiratory protection if ventilation is insufficient.

Spill management

  • Use personal protective equipment including chemical resistant gloves and eye protection.
  • Do not flush into surface water or sanitary sewer system.
  • Soak up with inert absorbent material and dispose as hazardous waste.
  • Part 2/2: Use mechanical handling equipment to avoid dust generation.
  • Highly water contaminating - prevent environmental release.
  • Never mix with acids - may generate toxic chlorine gas.
  • Dispose according to waste code 160506 (hazardous laboratory chemicals).

Special warnings

  • Two-part system - each part has different hazards and handling requirements.
  • Part 1/2 (Sample cuvette): Contains sodium hydroxide (<0.2%), pH 12.5, causes severe burns (R35).
  • Part 2/2 (DosiCapZip): Contains toxic sodium nitroprusside (12%) - toxic if swallowed (R25).
  • Generates toxic gas - contact with acids liberates toxic gas (cyanide compounds).
  • Aquatic toxicity: Very toxic to aquatic organisms with long-lasting effects.
  • Storage: Keep in dry, cool place (2-8°C for refrigerated storage).
  • Highly water contaminating class 3 - prevent release to environment.
  • Chlorine generation: Part 2/2 may develop chlorine if mixed with acidic solutions.
  • Professional use only - water analysis reagent for laboratory use.
  • Disposal: Local Hach agencies will accept used cuvettes for proper disposal.
